BS EN 1875-3 is the third part of an international standard that discusses the attributes of good quality rubber or plastic-coated fabrics.
BS EN 1875-3 specifies test conditions and the procedure to be followed for determining the tear strength of a trapezoidal specimen of rubber- or plastics-coated fabric, using a tensile testing machine.
BS EN 1875-3 may be carried out:
BS EN 1875-3 on tear strength for rubber or plastic-coated fabrics is useful for:
Rubber and plastic are used extensively in many applications and products, either alone or in combination with other materials. Tearing is among the more usual ways of destruction for many thin materials such as paper, coated or uncoated textiles, plastics films, and leather. Therefore, knowledge of the resistance of these materials to this type of behavior is important.
The tearing can result from very different circumstances, hence, the large number of test methods that have been developed to predict the behavior of the materials in various situations.
BS EN 1875-3 lays down the specifications for the trapezoidal method to determine the tear strength of the rubber or plastic-coated fabrics. This helps users to get the tear strength of a coated fabric, in order to check its capacity to resist a force tending to separate its constituent threads before it breaks.
BS EN 1875-3 mentions the principle of the trapezoidal test method, apparatus used in the test, sample preparation as well as a detailed test procedure to determine tear strength. This guides users to carry out the test procedure to ensure the high quality and reliability of the coated fabric made of rubber or plastics.
